More historic than 14% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Pahoa is more historic than 14% of U.S. towns. Its share of homes from before 1940 holds the grade up; its age pulls it down.
Few Hawaii towns list much on the Register (a typical Hawaii town has 0.0 per 10,000 residents, the U.S. 2.4), so Pahoa’s 0.0 sits below most of its state (28% of Hawaii towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

The Pahoa post office opened in 1903, the earliest record of the town by name (U.S. post office records).
Pahoa is more historic than 14% of U.S. towns. The History grade combines the town’s founding era, the share of homes built before 1940 and its National Register listings. It’s a character grade, so it isn’t part of the overall grade. How it works.
7% of Pahoa’s homes were built before 1940 (Census estimate, ±4.9 points), against a typical 1.7% for a Hawaii town; the median home was built in 1973.
